Common Repair Uses

  • Restore proper wheel hub and suspension mounting alignment during repair

Installation Notes and Tips

Verify the OE number, side, and model year before installation. Confirm the paired article number V10-5128 when servicing the opposite side or comparing left-right components. Because steering knuckle fitment is position-specific, match the front left application exactly to the vehicle and suspension configuration before assembly.
